2004 ES.....Every once in a great while i'll go to start my car while the engine is cold and I go to turn the key and it acts like it wants to start but doesnt actually start the motor. but when I let off and turn the key again immediately, the car starts right up. Maybe once a month it does this. No battery problems or starter issues that I could find. Could any of you guys help me with this?
It could be the crank angle sensor.
It is located behind a plastic cover next to the harmonic balancer.
I have had this failure and it is reported as code U1120 by the MUT3 tester.
But that code says CAN BUS ERROR.
That confused us for a long time because the auto trans reports it.
Don't get caught...it's an easy fix and the part is about a hundred dollars.
yea i had the same problem with mine and i went to autozone and checked it out, and it was the crankshaft position sensor
Some people have reported that the battery voltage gets low near the end of the bettery's life and produces a crank sensor CEL
